Ya know, having an older harley can start to cost some cash,after spending nearly 2K to fix my trans,and finding out I still have this noise? how much is this one going to cost.
FULL SPEED AHEAD,DAMN THE TORPEDOS!
If your trying to keep your 20 year old bike on the road. KEEP UP THE GOOD WORK. as the bikes get a bit older at least you have a scoot thats not like all the others eh?
Holey Crap Ironhead, you put a grade 5 bolt in your rear brake hub? You need at least a 125 ksi bolt there! You better rethink that decision sir! Cheap can be fatal in that area....
it didn't take much thinking.... the H-D Shop made the suggestion, and 2... it would take 1 hellova lot of torque to snap that bolt.
I may however replace it with a stainless bolt.
The shear strength of a grade 5 compared to a grade 8 is about 7. You hight as well leave it an empty hole. The increased shear on the brake rotor/hub from a five axis center to a four axis center load with the 20% offset in rotational force or equilized torque load is substantial. Granted the fact that the shear of the four remaining bolts is tremendous, the comparison with all five is also a very great amount. Some grade 8 bolts go as high as 160 ksi so my comparison figures may be conservative.
But; two of the grade five bolts would probably hold the entire shear load of the brake rotor/hub so yes, you are quite safe; so I may learn to keep my opinions to myself yet!
